ECPSR086370-001工控卡件，ABB使用配置手册

IndustryPack（IP）接口MVME162上的IPIC ASIC支持四个IndustryPack（IP）接口；这些可以从前面板访问。请参阅IPIC编程MVME162嵌入式控制器程序员参考指南中的模型IP接口的详细信息。请参阅MVME162嵌入式控制器支持IP连接器引脚分配信息手册。以太网接口Intel 82596CA LAN控制器用于实现以太网收发器接口。82596CA使用DMA访问本地RAM执行其正常功能的操作。

ECPSR086370-001工控卡件因为82596CA的内部缓冲区和VMEbus有一个未定义的延迟周期，即缓冲区如果DMA编程为访问VMEbus，则可能发生溢出。因此，82596CA不应编程为访问VMEbus。每个MVME162分配一个以太网站地址。地址是$08003E2xxxxx，其中xxxxx是分配给电路板（即每个MVME162对于xxxxx具有不同的值）。每个MVME162都有一个以太网站地址，该地址显示在附加的标签上至背板连接器P2。此外，包括以太网的六个字节站点地址存储在BBRAM配置区域中。也就是说，08003E2xxxxx存储在BBRAM中。地址为$FFFC1F2C，上层可以读取四个字节（08003E2x）。在地址为$FFFC1F30时，下两个可以读取字节（xxxx）。请参阅BBRAM/TOD时钟内存映射第3章中的说明。MVME162调试器能够检索或设置以太网站地址。如果BBRAM中的数据丢失，请使用背板标签上的数字将其恢复到连接器P2。以太网收发器接口位于MVME162主模块上。MVME712系列上有一个行业标准的DB15连接器过渡模块。MCchip为82596CA提供支持功能。请参阅82596CA用户指南和MVME162嵌入式控制器程序员指南有关详细编程信息的参考指南。请参阅MVME712-12、MVME712-13、MVME712A、MVME712AM和MVME712B过渡模块和LCP2适配器板用户手册或MVME712M引脚分配的过渡模块和P2适配器板用户手册转换模块以太网连接器。

IndustryPack (IP) Interfaces

The IPIC ASIC on the MVME162 supports four IndustryPack (IP) interfaces;

these are accessible from the front panel. Refer to the IPIC Programming

Model in the MVME162 Embedded Controller Programmer’s Reference Guide for

details of the IP interface. Refer to the MVME162 Embedded Controller Support

Information manual for the pin assignments of the IP connectors.

Ethernet Interface

The Intel 82596CA LAN controller is used to implement the Ethernet

transceiver interface. The 82596CA accesses local RAM using DMA

operations to perform its normal functions. Because the 82596CA has small

internal buffers and the VMEbus has an undefined latency period, buffer

overrun may occur if the DMA is programmed to access the VMEbus.

Therefore, the 82596CA should not be programmed to access the VMEbus.

Every MVME162 is assigned an Ethernet station address. The address is

$08003E2xxxxx, where xxxxx is the unique 5-nibble number assigned to the

board (i.e., every MVME162 has a different value for xxxxx).

Each MVME162 has an Ethernet station address displayed on a label attached

to backplane connector P2. In addition, the six bytes including the Ethernet

station address are stored in the BBRAM configuration area. That is,

08003E2xxxxx is stored in the BBRAM. At an address of $FFFC1F2C, the upper

four bytes (08003E2x) can be read. At an address of $FFFC1F30, the lower two

bytes (xxxx) can be read. Refer to the BBRAM/TOD Clock memory map

description in Chapter 3. The MVME162 debugger has the capability to

retrieve or set the Ethernet station address.If the data in the BBRAM is lost, use the number on the label on backplane

connector P2 to restore it.

The Ethernet transceiver interface is located on the MVME162 main module.

An industry-standard DB15 connector is located on the MVME712 series

transition module.

The MCchip provides support functions for the 82596CA. Refer to the

82596CA user’s guide and to the MVME162 Embedded Controller Programmer’s

Reference Guide for detailed programming information. Refer to the

MVME712-12, MVME712-13, MVME712A, MVME712AM, and MVME712B

Transition Modules and LCP2 Adapter Board User’s Manual or the MVME712M

Transition Module and P2 Adapter Board User’s Manual for the pin assignments

of the transition module Ethernet connectors.
